I believe the answer is C.
93.53 - 21.41 = 72.12
If you simplify C, its answer becomes equivalent to the answer of the original problem:
(90 - 20) + (3 - 1) + (0.5 - 0.4) + (0.03 - 0.01)
70 + 2 + 0.1 + 0.02
72.12
We know
<h3>Option b is coreect</h3>
Answer:
It depends, Y or X have to be set up to get an actual number because you can simply plug any numbers.
You have to remember P.E.M.D.A.S. when doing problems like this.
Drew used PEMDAS so we know he isn't wrong. However, Sam didn't use PEMDAS. She multiplied 2&5 instead of raising 5 to the second.
The correct answer for Sams' problem would be 30.
Hope this helps! :)
Step-by-step explanation:
Vamos simplificar passo a passo.
k2-6k4-(3k4+k2+2)
Distribua o sinal negativo:
=k2-6k4+-1(3k4+k2+2)
=k2+-6k4+-1(3k4)+-1k2+(-1)(2)
=k2+-6k4+-3k4+-k2+-2
Combine os termos semelhantes:
=k2+-6k4+-3k4+-k2+-2
=(-6k4+-3k4)+(k2+-k2)+(-2)
=-9k4+-2
Responda:
=-9k4-2
